The present invention, relates to apparatus.

a designed for the-purPQset-of joining wires bytwistingthemtogetl1e1'.--- Such a tool can be employed in many processes and'isl par-i ticularly useful in; electricaltwork f or ex ample such -a gtooi ican be employed very conveniently for; joining; together-thewiresof a multiple stranded cable or-under other conditions :whereitaeis necessary to connect a number of pairs ofiwiresf.

at the completion of thetwisting-operation:

The apparatus preferably atakes the form of z a tool that; can be;conveniently; heldin thehands and manipulated for j oining; wires inrconfined-k spaces, for example sin j un'ction' Briefly T stated theinvention com-p rises. the use of aeoile'd springada'pted tobe initiallyWound up by hand and togbe released .by a trigger in order :to efie'ct:thetwrstmg top- 20 ation'. This spring is arranged to revol ve' eitherdirectly- "or thro'u'gh ge'aring -:a "qnein ber in engagement with thewires :to be twisted; A cutter' may be prov'idedfor severing theextremities ofithe twisted Wires My invention is shown by way'of example in-"the accompanying drawings," in which Figurefl shows a'longitudinalfsection of the apparatus infthe form of a tool con-j,veniently held in the hands and man pulatedfor joining wires in tightplaces;

The rotation thus given to said the first described tool.

pinion 4 is transmitted to the twisting pinion 13 mounted on the innerend of the wire nozzle 18 carried on their'ont wall of the box 2. Thisnozzle 18'is set ofithe central axisoi the tool so that the rotationvofthe pinion is not concentric withv the cutter pinion 12. The pinion 13"is" provided with a central elongated opening 22 designed to receivethe'wires which have been p'assed through the nozzle. lt will be easilynn-5 derstood that the rotation givento the pinion 13 will twist thewirestherein to-t gether. The twisted ends of the wires may projectthrough the opening 23 inthe stationary cutterpinion .12 and owing tothe In Figures9'and 10 I show an alternative formfofthe tool in which ashort knurled cylindrical box 27' is substituted'for the relatively longhandle'l of, the tool shown in Figure 1. The triggeroperating member 5in this alternative form of tool is preferably mounted on the peripheryof the 'cylin drical box 2 and not on the handle 11 as in The internalmembers of the'alternative ,form of tool are identical in form and.position with these members in the said long handle tool. 7

The drawings show the preferred embodiment of my invention in'aflportable form. It is apparent however that the'invention may beapplied in a'variety of forms and other types of motors than the springshown in the drawings may be usedj The claims are intended to include afull range of equivalents.
